Collaborative Art Practices in HE: Mapping and Developing Pedagogical Models
No full textThis project asks ‘How is interdisciplinary collaboration "taught" in HE institutions?’ and ‘What pedagogical models can be identified and developed?’
Performing and Creative Arts departments in HE institutions engage students in collaborative practice within a singular discipline or across disciplines, through interdisciplinary or hybridised art forms, as curricula or extra-curricula activity. Where students are engaged with interdisciplinary collaboration within the curriculum, tuition may involve case studies of collaborative partnerships, psychometric tests, a trial and error approach to throwing creative individuals together, or any combination of these.
This project aims to bring together ideas and modes of practices used in HE institutions and to present, as far as is possible, an overview of the current practices where interdisciplinary collaboration is a focal point of the learning activity.
In brief, and in the context of Performing and Creative Arts departments in HE institutions, this development project aims to:
Take a snapshot of current practice in HE
Construct typologies of modes of practice
Consider how pedagogies may be developed
Disseminate documentation setting out, and commenting on, pedagogical approaches to collaborative practic
Participation of c-FLIP in NLRP3 and AIM2 inflammasome activation
No full textCellular FLICE-inhibitory protein (c-FLIP) is an inhibitor of caspase-8 and is required for macrophage survival. Recent studies have revealed a selective role of caspase-8 in noncanonical IL-1 beta production that is independent of caspase-1 or inflammasome. Here we demonstrated that c-FLIPL is an unexpected contributor to canonical inflammasome activation for the generation of caspase-1 and active IL-1 beta. Hemizygotic deletion of c-FLIP impaired ATP-and monosodium uric acid (MSU)-induced IL-1 beta production in macrophages primed through Toll-like receptors (TLRs). Decreased IL-1 beta expression was attributed to a reduced activation of caspase-1 in c-FLIP hemizygotic cells. In contrast, the production of TNF-alpha was not affected by downregulation in c-FLIP. c-FLIPL interacted with NLRP3 or procaspase-1. c-FLIP is required for the full NLRP3 inflammasome assembly and NLRP3 mitochondrial localization, and c-FLIP is associated with NLRP3 inflammasome. c-FLIP downregulation also reduced AIM2 inflammasome activation. In contrast, c-FLIP inhibited SMAC mimetic-, FasL-, or Dectin-1-induced IL-1 beta generation that is caspase-8-mediated. Our results demonstrate a prominent role of c-FLIPL in the optimal activation of the NLRP3 and AIM2 inflammasomes, and suggest that c-FLIP could be a valid target for treatment of inflammatory diseases caused by over-activation of inflammasomes
Detrital zircon and apatite (U‐Th)/He geochronology of intercalated baked sediments: a new approach to dating young basalt flows
No full textSimple numerical models suggest that many basaltic lava flows should sufficiently heat the sediments beneath them to reset (U‐Th)/He systematics in detrital zircon and apatite. This result suggests a useful way to date such flows when more conventional geochronological approaches are either impractical or yield specious results. We present here a test of this method on sediments interstratified with basalt flows of the Taos Plateau Volcanic Field of New Mexico. Nineteen zircons and apatites from two samples of baked sand collected from the uppermost 2 cm of a fluvial channel beneath a flow of the Upper Member of the Servilleta Basalt yielded an apparent age of 3.487 ± 0.047 Ma (2 SE confidence level), within the range of all published 40Ar/39Ar dates for other flows in the Upper Member (2.81–3.72 Ma) and statistically indistinguishable from the 40Ar/39Ar dates for basal flows of the Upper Member with which the studied flow is broadly correlative (3.61 ± 0.13 Ma). Given the high yield of 4He from U and Th decay, this technique may be especially useful for dating Pleistocene basalt flows. Detailed studies of the variation of (U‐Th)/He detrital mineral dates in sedimentary substrates, combined with thermal modeling, may be a valuable tool for physical volcanologists who wish to explore the temporal and spatial evolution of individual flows and lava fields.</p
Preface
No full textThe MDEF Workshop has been held at the University of Urbino since 2000. The 2014 Workshop is particularly dedicated to Carl Chiarella for his 70th birthday. As the second home (along with the University of Bielefeld, another second home), Carl visited Urbino in 1998 for the first time and the visit has become an almost annual event since then. In order to commemorate the occasion, a number of Carl’s colleagues from around the world gladly agreed to contribute chapters to a special book dedicated to this event. The book is the outcome of this process. It contains the latest developments in nonlinear economic dynamics, financial market modeling, and quantitative finance, the three most active research areas Carl has been involved in

Cross section of He-3(He-3,2p)He-4 measured at solar energies
No full textWe report on the results of the He-3(He-4,2p)He-4 experiment at the underground accelerator facility LUNA (Gran Sasso). For the first time the lowest projectile energies utilized for the cross section measurement correspond to energies below the center of the solar Gamow peak (E-o=22 keV). The data provide no evidence for the existence of a hypothetical resonance in the energy range investigated. Although no extrapolation is needed anymore (except for energies at the low-energy tail of the Gamow peak), the data must be corrected for the effects of electron screening, clearly observed the first time for the He-3(He-3,2p)He-4 reaction. The effects are, however, larger than expected and not understood, leading presently to the largest uncertainty on the quoted S-b(0) value for bare nuclides (=5.40 MeV b
Introduction
No full textThis book reflects the state of the art on nonlinear economic dynamics, financial market modelling and quantitative finance. It contains eighteen papers with topics ranging from disequilibrium macroeconomics, monetary dynamics, monopoly, financial market and limit order market models with boundedly rational heterogeneous agents to estimation, time series modelling and empirical analysis, and from risk management of interest-rate products, futures price volatility and American option pricing with stochastic volatility to evaluation of risk and derivatives of electricity market. The book illustrates some of the most recent research tools in these areas and will be of interest to economists working in economic dynamics and financial market modelling, to mathematicians who are interested in applying complexity theory to economics and finance, and to market practitioners and researchers in quantitative finance interested in limit order, futures and electricity market modelling, derivative pricing and risk management
Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.

Investigation of Lagrangian coherent structures in a wake-induced boundary layer transition
No full textThe evolution of coherent structures in a flat plate boundary layer transition induced by the cylinder wake is investigated using the particle image velocimetry (PIV) technique. The finite-time Lyapunov exponent (FTLE), which characterizes the amount of stretching about the flow trajectory, is used to extract the Lagrangian coherent structures. It is revealed that secondary vortex is induced by the cylinder wake vortices in the near wall region,which would evolve into hairpin vortex as it convects downstream. The subsequent evolvement of the hairpin vortex, characterized by the regeneration of offspring hairpin vortex upstream of it, leads to the appearance of the hairpin packet and the boundary layer finally reaches a turbulent state
